Description

有機發光二極體照明裝置 Organic light emitting diode lighting device

本發明是有關於一種照明裝置，且特別是有關於一種有機發光二極體照明裝置。 The present invention relates to a lighting device, and more particularly to an organic light emitting diode lighting device.

有機發光二極體具有自發光、低耗電、高反應速率等優點，已吸引了顯示及照明領域應用的廣泛注意。有機發光二極體是以電激發螢光或磷光有機化合物的發光層來產生光線。 Organic light-emitting diodes have the advantages of self-luminescence, low power consumption, high reaction rate, etc., and have attracted extensive attention in the field of display and illumination. The organic light-emitting diode generates light by electrically exciting a fluorescent layer of a fluorescent or phosphorescent organic compound.

現有的有機發光二極體裝置大多是以導電薄膜為電極來傳輸電流至發光層，容易受限於電阻值而難以傳輸大電流，並導致無可避免的功率損失。尤其在照明領域，此問題會更加明顯。因此，為了傳輸大電流，會利用額外的分流電極來輔助大電流的傳送。 Most of the existing organic light-emitting diode devices use a conductive film as an electrode to transmit current to the light-emitting layer, which is easily limited by the resistance value and is difficult to transmit a large current, and causes inevitable power loss. Especially in the field of lighting, this problem will become more apparent. Therefore, in order to transmit a large current, an additional shunt electrode is utilized to assist in the transmission of large currents.

如圖1所示，一種有機發光二極體照明裝置的剖視示意圖。基板11上依序形成有透明電極12以及分流電極13。分流電極13與透明電極12電連接。由於分流電極13的厚度明顯大於透明電極12，利用低阻抗的分流電極13來傳輸大電流，可有效地避免功率損失。 FIG. 1 is a schematic cross-sectional view of an organic light emitting diode illumination device. A transparent electrode 12 and a shunt electrode 13 are sequentially formed on the substrate 11. The shunt electrode 13 is electrically connected to the transparent electrode 12. Since the thickness of the shunt electrode 13 is significantly larger than that of the transparent electrode 12, the low-current shunt electrode 13 is used to transmit a large current, and power loss can be effectively avoided.

然而，由於分流電極13加上絕緣層14的厚度，遠大於有機發光層15或金屬電極16的厚度，導致蒸鍍於基板11上之有機發光層15產生厚度不均勻的現象，並導致後續蒸鍍於有機發光層15上的金屬電極16在轉折處產生裂縫17的現象。 However, since the thickness of the shunt electrode 13 plus the insulating layer 14 is much larger than the thickness of the organic light-emitting layer 15 or the metal electrode 16, the organic light-emitting layer 15 evaporated on the substrate 11 is uneven in thickness, and causes subsequent steaming. The phenomenon in which the metal electrode 16 plated on the organic light-emitting layer 15 generates the crack 17 at the turning point.

本發明的一目的是在提供一種有機發光二極體照明裝置，可解決上述有機發光層之厚度不均及電極在轉折處發生裂縫的問題。 An object of the present invention is to provide an organic light emitting diode illumination device which can solve the problem of uneven thickness of the organic light emitting layer and cracking of the electrode at the turning point.

為讓本發明之上述和其他目的、特徵和優點能更明顯易懂，下文特舉較佳實施例，並配合所附圖式，作詳細說明如下。 The above and other objects, features and advantages of the present invention will become more <RTIgt;

圖2為依據本發明之一實施例之有機發光二極體照明裝置20的剖視示意圖。如圖所示，有機發光二極體照明裝置20包含基板21、導線22、絕緣層23、第一電極層24、有機發光層25，以及第二電極層26。 2 is a cross-sectional view of an organic light emitting diode illumination device 20 in accordance with an embodiment of the present invention. As shown, the organic light-emitting diode illumination device 20 includes a substrate 21, a wire 22, an insulating layer 23, a first electrode layer 24, an organic light-emitting layer 25, and a second electrode layer 26.

基板21為透明的玻璃或塑膠材質。導線22位在基板21上。導線22為金屬材質。導線22具有二由基板21上表面向上延伸的側面220，以及連接二側面220的頂緣且遠離基板21的頂面221。頂面221的至少一部分向上露出於絕緣層23之外。 The substrate 21 is made of transparent glass or plastic. The wire 22 is positioned on the substrate 21. The wire 22 is made of metal. The wire 22 has two side faces 220 extending upward from the upper surface of the substrate 21, and a top edge 221 connecting the top edges of the two side faces 220 away from the substrate 21. At least a portion of the top surface 221 is exposed upward beyond the insulating layer 23.

絕緣層23位於基板21上，並位於導線22的二側且與導 線22的二側面220相接。絕緣層23具有一遠離基板21的上表面231，且絕緣層23之厚度大致等於導線22之厚度，使絕緣層23之上表面231大致對齊於導線22之頂面221。絕緣層23為至少部分透明的無機材質或有機材質。無機材質可為氮化矽或二氧化矽等，而有機材質可為BCB或PC403等聚合物。 The insulating layer 23 is located on the substrate 21 and is located on both sides of the wire 22 and is guided The two sides 220 of the wire 22 meet. The insulating layer 23 has an upper surface 231 away from the substrate 21, and the thickness of the insulating layer 23 is substantially equal to the thickness of the wires 22 such that the upper surface 231 of the insulating layer 23 is substantially aligned with the top surface 221 of the wires 22. The insulating layer 23 is an at least partially transparent inorganic or organic material. The inorganic material may be tantalum nitride or cerium oxide, and the organic material may be a polymer such as BCB or PC403.

第一電極層24覆蓋於導線22之頂面221及絕緣層23的上表面231上。第一電極層24為至少部分透明的透明導電膜，並且與導線22之頂面221形成電連接。有機發光層25覆蓋於第一電極層24上。有機發光層25例如包含電子傳輸層(electron transport layer)、電致發光層(electroluminescent layer)、以及電洞傳輸層(hole transport layer)。第二電極層26位於有機發光層25上。第二電極層26例如為不透光的金屬材質薄膜，或者，亦可為透光的透明導電膜。需特別說明的是，第一電極層24、有機發光層25、以及第二電極層26三者在導線22及絕緣層23的上方彼此平行地連續延伸，沒有斷面及轉折。 The first electrode layer 24 covers the top surface 221 of the wire 22 and the upper surface 231 of the insulating layer 23. The first electrode layer 24 is an at least partially transparent transparent conductive film and is electrically connected to the top surface 221 of the wire 22. The organic light emitting layer 25 covers the first electrode layer 24. The organic light-emitting layer 25 includes, for example, an electron transport layer, an electroluminescent layer, and a hole transport layer. The second electrode layer 26 is on the organic light emitting layer 25. The second electrode layer 26 is, for example, a metal film that is opaque to light, or may be a light-transmissive transparent conductive film. It should be noted that the first electrode layer 24, the organic light-emitting layer 25, and the second electrode layer 26 continuously extend parallel to each other above the wires 22 and the insulating layer 23, and have no cross-section and transition.

當施加電壓時，電流會從導線22流至第一電極層24，再經由有機發光層25至第二電極層26。帶負電的電子由第二電極層26移動至有機發光層25，同時帶正電的電洞會由第一電極層24移動至有機發光層25。當帶負電的電子與帶正電的電洞在有機發光層25相遇，兩者會再結合(recombine)並放出光子，並經由第一電極層24、絕緣層23以及基板21並向外界發出。 When a voltage is applied, current flows from the wire 22 to the first electrode layer 24 and then through the organic light-emitting layer 25 to the second electrode layer 26. The negatively charged electrons are moved from the second electrode layer 26 to the organic light emitting layer 25 while the positively charged holes are moved from the first electrode layer 24 to the organic light emitting layer 25. When the negatively charged electrons and the positively charged holes meet at the organic light-emitting layer 25, the two recombine and emit photons, and are emitted to the outside through the first electrode layer 24, the insulating layer 23, and the substrate 21.

由於導線22之頂面221大致對齊絕緣層23的上表面231，兩者大致可構成一個平整的平面，使第一電極層24、有機發光層25、以及第二電極層26三者在導線22及絕緣層23的上彼此平行地連續延伸，由於沒有轉折，第一電極層24、 有機發光層25、以及第二電極層26三者的厚度均勻且不會導致裂縫的情況發生。藉此，可有效提高有機發光二極體照明裝置20之發光均勻性。 Since the top surface 221 of the wire 22 is substantially aligned with the upper surface 231 of the insulating layer 23, the two may substantially form a flat plane, such that the first electrode layer 24, the organic light-emitting layer 25, and the second electrode layer 26 are on the wire 22. And the upper layers of the insulating layer 23 extend continuously in parallel with each other, since there is no turning, the first electrode layer 24, The thicknesses of the organic light-emitting layer 25 and the second electrode layer 26 are uniform and do not cause cracks. Thereby, the uniformity of illumination of the organic light-emitting diode illumination device 20 can be effectively improved.

適用於製作絕緣層23的形成方式可為蒸鍍、濺鍍等沉積方法，且本發明不以此為限。如圖3所示，不同的沉積方法及沉積時的條件的可能導致絕緣層23之上表面231略低或略高於導線22之頂面221。但需注意的是，絕緣層23之上表面231與導線22之頂面221的高度差可限定在小於100nm，以避免較大轉折導致裂縫的情況發生。 The method for forming the insulating layer 23 may be a deposition method such as vapor deposition or sputtering, and the invention is not limited thereto. As shown in FIG. 3, different deposition methods and conditions at the time of deposition may cause the upper surface 231 of the insulating layer 23 to be slightly lower or slightly higher than the top surface 221 of the wire 22. It should be noted, however, that the difference in height between the upper surface 231 of the insulating layer 23 and the top surface 221 of the wire 22 can be limited to less than 100 nm to avoid the occurrence of cracks due to a large turning.

圖4是依據本發明之一實施例之有機發光二極體照明裝置的上視示意圖。本實施例之有機發光二極體照明裝置大致與圖2的實施例相同，不同之處在於絕緣層23之厚度較導線22為薄，第一電極層24覆蓋絕緣層23之上表面，但並未覆蓋於導線22之頂面221，而是位於導線22之兩側且分別連接至導線22之兩側面220上。 4 is a top plan view of an organic light emitting diode lighting device in accordance with an embodiment of the present invention. The organic light emitting diode illumination device of the present embodiment is substantially the same as the embodiment of FIG. 2, except that the thickness of the insulating layer 23 is thinner than the wire 22, and the first electrode layer 24 covers the upper surface of the insulating layer 23, but The top surface 221 of the wire 22 is not covered, but is located on both sides of the wire 22 and is connected to the two sides 220 of the wire 22, respectively.

在本實施例中，絕緣層23之厚度加上第一電極層24之厚度大致等於導線22之厚度，使導線22之頂面221大致對齊第一電極層24的上表面，導線22之頂面221與第一電極層24之上表面兩者大致可構成一個平整的平面，使有機發光層25以及第二電極層26在導線22及第一電極層24的上方彼此平行地連續延伸，沒有斷面及轉折。 In the present embodiment, the thickness of the insulating layer 23 plus the thickness of the first electrode layer 24 is substantially equal to the thickness of the wire 22 such that the top surface 221 of the wire 22 is substantially aligned with the upper surface of the first electrode layer 24, and the top surface of the wire 22 221 and the upper surface of the first electrode layer 24 can form a flat plane substantially, so that the organic light-emitting layer 25 and the second electrode layer 26 extend continuously parallel to each other above the wire 22 and the first electrode layer 24 without breaking. Face and turning.

圖5是依據本發明之一實施例之有機發光二極體照明裝置20的上視示意圖。在本實施例中，導線22之數量為複數，各導線22為直線狀且平行地排列於基板21上。並且，第一電極層24實際上具有多個分別連接至導線22的電極區塊241。需注意的是，實際實施時，導線22的數量及第一電極層22的 分佈及形狀皆不以圖5所示為限。 FIG. 5 is a top plan view of an organic light emitting diode illumination device 20 in accordance with an embodiment of the present invention. In the present embodiment, the number of the wires 22 is plural, and the wires 22 are linear and arranged in parallel on the substrate 21. Also, the first electrode layer 24 actually has a plurality of electrode blocks 241 that are respectively connected to the wires 22. It should be noted that, in actual implementation, the number of wires 22 and the first electrode layer 22 The distribution and shape are not limited to those shown in FIG.

圖6是依據本發明之一實施例之有機發光二極體照明裝置20之製作方法的流程圖。配合參考圖2及圖6，首先，在步驟110中，提供基板21。接著，在步驟120中，於基板21上形成導線22。然後，在步驟130中，於基板21上形成絕緣層23，且使絕緣層23露出導線22之頂面221的至少一部分。接著，在步驟140中，形成覆蓋導線22之頂面221及絕緣層23之上表面231之第一電極層24，且使第一電極層24與導線22之頂面221形成電連接。然後，在步驟150中，於第一電極層24上形成有機發光層25。最後，在步驟160中，於有機發光層25上形成第二電極層26，即完成本發明實施例之有機發光二極體照明裝置20的製作。 FIG. 6 is a flow chart of a method of fabricating an organic light emitting diode illumination device 20 in accordance with an embodiment of the present invention. Referring to FIG. 2 and FIG. 6, first, in step 110, the substrate 21 is provided. Next, in step 120, a wire 22 is formed on the substrate 21. Then, in step 130, an insulating layer 23 is formed on the substrate 21, and the insulating layer 23 is exposed to at least a portion of the top surface 221 of the wire 22. Next, in step 140, a first electrode layer 24 covering the top surface 221 of the wire 22 and the upper surface 231 of the insulating layer 23 is formed, and the first electrode layer 24 is electrically connected to the top surface 221 of the wire 22. Then, in step 150, an organic light-emitting layer 25 is formed on the first electrode layer 24. Finally, in step 160, the second electrode layer 26 is formed on the organic light-emitting layer 25, that is, the fabrication of the organic light-emitting diode lighting device 20 of the embodiment of the present invention is completed.

綜上所述，本發明至少具有以下優點： In summary, the present invention has at least the following advantages:

由於使導線22之頂面221大致對齊絕緣層23的上表面231或是大致對齊第一電極層24的上表面，兩種作法皆大致可構成一個平整的平面，使有機發光層25以及第二電極層26兩者在導線22及絕緣層23上彼此平行地連續延伸。由於沒有轉折，有機發光層25以及第二電極層26兩者的厚度均勻且不會導致裂縫的情況發生。藉此，可有效提高有機發光二極體照明裝置20之發光均勻性。 Since the top surface 221 of the wire 22 is substantially aligned with the upper surface 231 of the insulating layer 23 or substantially aligned with the upper surface of the first electrode layer 24, both methods can substantially form a flat plane, so that the organic light-emitting layer 25 and the second layer Both of the electrode layers 26 continuously extend in parallel with each other on the wires 22 and the insulating layer 23. Since there is no turning, the thickness of both the organic light-emitting layer 25 and the second electrode layer 26 is uniform and does not cause cracks. Thereby, the uniformity of illumination of the organic light-emitting diode illumination device 20 can be effectively improved.
